While your specimen may perhaps be an unnamed selection (grafted clone) note that in this instance the name drummondii belongs to a botanical var., used for the southern red maple (representing the species in the bottom end of its wild range) - and not to a cultivar 'Drummondii': "Leaf larger, often broader than long, more or less white and hairy beneath, thicker, usually with five deeper lobes; seeds larger, to 2" (instead of 1"[or less]) long." --A.L. Jacobson, North American Landscape Trees
